IMPROVEMENT IN CHANNEL OPENERS AND MOLDERS FOR BOOTS AND SHOES..

Specication forming part of Letters Patent N o. 168,045, dated September21, 1875; application filed July e9, 18754.

To all whom it may concern:

Be it known that l, THOMAS L. MILLER, of the city and county ot'Philadelphia, in the State of Pennsylvania, have inventeda GombinedChannel Opener andMolderof Shoe- Soles, of which the following is aspecification: Y

My invent-ion consists mainly in the combination of a revolvingchannel-opener with a wheel having a square edge, which revolves inapl-ane at right angles to that ofthe opener, for forming the marginalsurface outside of the channel, a like wheel, having a square edge,revolving in a plane' at right angles to the latter wheel, for guidingthe edge of the sole, thereby regulating the Width ofsaid marginalsurface, and gaging the distance ofthe channel from the edge of the sole5 and a wheel with a round edge revolving in a plane at right angles tothe-said gage-wheel, which presses toward the channel-opener, and thewheel which l'orms the marginaly surface for bending the sole, ashereinafterfully described.l

The channel-opener is on one end of a rod, which is situated in the boreof a revolving shaft, which also contains a wire spring, which forcesthe channel-opener forward after the operation of opening'the channeland molding the sole, and the bending wheel has been thrown outward fromthe solethereby relieving the sole from its connectionwith all thewheels, to be' readily removed from the channel-opener, the throwingback ofthe said bending-wheel heilig eifected by the movement of alever, with which the shaft of the said wheel is connected.

In the accompanying drawings, Figure l is a plan view of the combinedchannel opener and iuolder. Fig. 2 is a side elevation of the saine.Fig. 3 is a longitudinal 'section of the sole F. l

Like letters of reference in all the figures iudica-te the same parts.

A is a stand, with which the several part-s i ofthe machine areconnected. Its uprights a a are slotted to receive th`e bearings ofthehorizontal revolving' shafts B B1 B2. U is a revolving channel-oponer onthe outer end of the stein D, situated in the bore d ofthe shaft B. E isa wheel on the vertical stud-shaft B3, whose projecting edge f bearsagainst the sole k, whichpasses through the cheeks l l ofthe stand'A..This wheel has a rounded edge for molding the part m of the sole. Thelever J" Y is adjustable, by means of the nut K, on the upper end of therod L, which projects upwardl rom the top of thestandard A, whereby tovary the dist-ance'between the periphery of the wheel I an'dthat of thewheel E, to regulate the thickness of the sole at its edge. M is aspringfwhich surrounds the' rod l, and bears the free end of the leverupward against the nut, but yields' sufficiently to the reaction of thesole, to prevent a too compact condensation of the same. l

The shaft B2, which inthe present arrangement of thegearing is thedriving-shaft, has a band-wheel, N, which connects by means of the bandO withl the Wheel N on the shaft B, A

for revolving the'chanuel-opener C.

Motion is communicated from the driving; shaft B2 to the shaft B1, bymeans ofthe spurwheels P and P on saidshafts, respectively, to revolvethe gage-wheel'H, which in its revolutions revolves the wheel E, by itsinner side, at the periphery of the wheel, bearing against theperipheral surface of the rabbet 'm of said' wheel E. The molding-wheelI is revolved by means of the geared connection of its shaft B4 with thedriving-shaft, through the miter-Wheels Q and Q.

The stem D of the channel-opener has a slot,y n, (seen in Fig. 2,) whichextends over the pin' p, whose ends are fast; in the shell of the shaftB, to admit of th'e inward movement oftheK stem. R is a treadle-strap,whose ends are hung on the rod q, which passes through the free end ofthe lever J When a sole is to be placed in the machine for opening thechannel and molding its edge,

the free end of the lever is borne down, whereby the wheel I is thrownbackward out of the way, for connecting the channel-opener with thechannel. Then the lever is allowed to come into the position shown inFig. 2, pressing the wheel I hard upon the sole, and causing theopposite side of the latterto bind hardagainst the edge of the wheel F,the spring M yielding to the pressure until the channel-opener is forcedinto its position. (Seen in Fig. 2.) Then, as chev crank S is turned ineither direction, the wheels E, H,1and I, and the chan nel-openerC, arerevolved, and the sole car- I claim as my invention- 1'. The combinationof the channel-opener C, gage-Wheel H, and molding-Wheels E and I,arranged and operating in relation to each other, substantially as andset forth.

2. The combination of the Wheel I and shaft B4 with the lever J,substantially as and for the purpose set forth.

3. The combination of the spring M with the hollow shaft B, andchannel-opener C, as

and for the purpose set forth.
